CVE-2026-28361Network attack vector

Cross-user token access via missing ownership filters

Published Mar 2, 2026 · Updated Mar 2, 2026

Authorization bypass in NocoDB before 0.301.3 allows remote authenticated users to access or invalidate other users' MCP tokens. McpTokenService.get(), regenerateToken(), and delete() select tokens by an attacker-supplied ID without filtering records by fk_user_id. Creator access to the same base and knowledge of a target token ID are required; impact is limited to scoped token disclosure and token invalidation.
